Command line foward engineering using a .mwb file? - command-line

Question

I need to be able to perform a forward engineering from a model located in a .mwb file. All of this from the command line as I would like to automate the process.
Can anyone please let me know if this is possible and if so how?

Answer 1

This is the output in the command line once you call WB with --help:
mysql-workbench [<options>] [<model file>]
Options:
--force-sw-render Force Xlib rendering
--force-opengl-render Force OpenGL rendering
--query <connection> Open a query tab to the named connection
--admin <instance> Open a administration tab to the named instance
--model <model file> Open the given EER model file
--script <script file> Execute the given Python or Lua script file
--run <script> Execute the given code in default language for GRT shell
--run-python <script> Execute the given code in Python
--run-lua <script> Execute the given code in Lua
--quit-when-done Quit Workbench when the script is done
--help, -h Show command line options and exit
--log-level=<level> Valid levels are: error, warning, info, debug1, debug2, debug3
--verbose Enable diagnostics output
--version Show Workbench version number and exit
I guess you can load your model using the --model option and then create an script that will perform the forward engineering and run it using the --run option and then instruct WB to exit once it finishes with the --quit-when-done option.
You can consult WB help to learn more about creating scripts as well as this guide.

Answer 2

You can actually automate this task with Python (or Lua) script - MySQL Workbench already has an interpreter under Scripting menu. Create a new script and use the stub:
# -*- coding: utf-8 -*-
import os
import grt
from grt.modules import DbMySQLFE
c = grt.root.wb.doc.physicalModels[0].catalog
DbMySQLFE.generateSQLCreateStatements(c, c.version, {
'GenerateDrops' : 1,
'GenerateSchemaDrops' : 1,
'OmitSchemata' : 1,
'GenerateUse' : 1
})
DbMySQLFE.generateSQLCreateStatements(c, c.version, {
DbMySQLFE.createScriptForCatalogObjects(os.path.dirname(grt.root.wb.docPath) + 'ddl.sql', c, {})
It does not actully run from command line, but I beleive you can run it with --run-script option.

This question is too old, but I found a project on github that make this, below the commands in cmd windows, and here the github repository and more linux sh file version.
Windows
#echo off
REM generate sql from mwb
REM usage: mwb2sql.bat {.mwb file} {output file}
SET WORKBENCH="C:\Program Files (x86)\MySQL\MySQL Workbench 6.0 CE\MySQLWorkbench.exe"
SET OUTPUT=%~f2
%WORKBENCH% ^
-open %~f1 ^
-run-python "import os;import grt;from grt.modules import DbMySQLFE as fe;c = grt.root.wb.doc.physicalModels[0].catalog;fe.generateSQLCreateStatements(c, c.version, {});fe.createScriptForCatalogObjects(os.getenv('OUTPUT'), c, {})" ^
-quit-when-done
